I haven't heard, when I used to fish it I had my best fishing late August but I know the skoke has some kings in it now, they should be stacking up out there. I have several friends who fish it hard, I'll see what they know.
The union launch is your best bet anyways, too small for my boat but you'll be just right. The power house launch is now native owned and operated, I've heard its $15 to launch there. If I were you I'd fish bald point which is right across from the union launch, there should be plenty of other boats around.
Its not a redhot fishery but you can have a good time there, with some patience you'll catch some nice fish. The canal is where my saltwater addiction began.
